Herald added a subscriber: mercurial-devel.
Herald added a reviewer: hg-reviewers.

REVISION SUMMARY
  I think the time has come. My main reason for wanting to do this is
  to force Mercurial developers to use Python 3 in their day-to-day work.
  This should help flush out any remaining Python 3 bugs.
  
  If this change is too controversial, we can revert it before the next
  release.
  
  .. bc::
  
    Makefile now uses `python3` instead of `python` by default. This
    means Mercurial will be built and run with Python 3 instead of
    Python 2.7 by default.
    
    To continue using Python 2, set the PYTHON variable. e.g.
    `make install PYTHON=python2.7`.
